Answer:

f^-1(x) = [(x + 1)/2]^⅓

Step-by-step explanation:

y = 2x³ - 1

Make x the subject

2x³ = y + 1

x³ = (y + 1)/2

x = [(y + 1)/2]^⅓

Interswitch variables

f^-1(x) = [(x + 1)/2]^⅓

An ice cream shop sells an empty cone for 4.00 plus an additional 1.25 per scoop of ice cream. You have 6.75 to spend. How many
DochEvi [55]

Answer:

2 scoops

Step-by-step explanation:

the flat fee is $4.00. 4+1.25=5.25. You have $6.75 to spend, so you can probably add on another scoop. 5.25+1.25=6.5. I was correct. To simplify, two scoops of ice cream without the cone is $2.50, but you will probably have a cone with your ice cream so that adds on $4.00. $4.00+$2.50=$6.50 and that is the max amount of ice cream scoops and cones since you cannot go over your budget.

If one half of an integer is added to one fifth of the next consecutive integer, the sum is 10. Find the integers.
Ivahew [28]
Let 1st integer be x and next consecutive be x+1
1/2•x + 1/5•(x+1) = 10
x/2 + x/5 + 1/5 = 10
-1/5 -1/5
x/2 + x/5 = 49/5
(x/2)•5/5 + (x/5)•2/2 = 49/5
5x/10 + 2x/10 = 49/5
7x/10 = 49/5
•10 •10
7x = 98
÷7 ÷7
x = 14 --> 1st integer
x+1 = 14+1 = 15 --> next consecutive integer

-5 = 1 / 3 ( -1 - w )<br> plz help with step by step answer
sweet [91]

Step-by-step explanation:

- 5 =  \frac{1}{3} ( - 1 - w) \\  \frac{1}{3} ( - 1 - w) =  - 5 \\   - 1 - w =  - 5 \div    \frac{1}{3}  \\  - 1 - w =  - 5 \times 3 \\  - 1 - w =  - 15 \\  - w =  - 15 + 1 \\   - w =  - 14 \\ w = 14
